aligning to relatively long (e.g. mammalian) genomes.  Bowtie 2 indexes the
genome with an FM Index to keep its memory footprint small: for the human

algorithms: BWA-backtrack, BWA-SW and BWA-MEM.  The first algorithm is
designed for Illumina sequence reads up to 100bp, while the rest two for
longer sequences ranged from 70bp to 1Mbp.  BWA-MEM and BWA-SW share similar
features such as long-read support and split alignment, but BWA-MEM, which is
the latest, is generally recommended for high-quality queries as it is faster
and more accurate.  BWA-MEM also has better performance than BWA-backtrack for
70-100bp Illumina reads.")

putative co-factors that provide specificity to each TF.  The framework
determines the genomic targets uniquely-bound by each TF, and identifies a
small set of co-factors that best explain the in vivo binding differences
between the two TFs.

COUGER uses classification algorithms (support vector machines and random
forests) with features that reflect the DNA binding specificities of putative
co-factors.  The features are generated either from high-throughput TF-DNA

FASTA/FASTQ files is mapping the sequences to reference genomes.  However, it
is sometimes more productive to preprocess the files before mapping the
sequences to the genome---manipulating the sequences to produce better mapping
results.  The FASTX-Toolkit tools perform some of these preprocessing tasks.")

     "PLINK is a whole genome association analysis toolset, designed to
perform a range of basic, large-scale analyses in a computationally efficient
manner.  The focus of PLINK is purely on analysis of genotype/phenotype data,
so there is no support for steps prior to this (e.g. study design and
planning, generating genotype or CNV calls from raw data).  Through
integration with gPLINK and Haploview, there is some support for the
subsequent visualization, annotation and storage of results.")

easily download the genomic locations of the transcripts, exons and cds of a
given organism, from either the UCSC Genome Browser or a BioMart

then stored in a local database that keeps track of the relationship between
transcripts, exons, cds and genes.  Flexible methods are provided for
extracting the desired features in a convenient format.")
